Question #: 2254

Question: BlackFoot CNC: Where should z-axis limit switches be placed?

Current Solution

The limit switch for the z-axis should be placed in a location where nothing can interfere with CNC process, now for our blackFoot, referring to step 115(https://www.buildyourcnc.com/blackFoot48v40.aspx#prettyPhoto/120/) it will be placed 1-1/4"(may be adjusted) down from the top wood piece(vacuum holder). So contact will be made from the location of the anti-backlash nut wood piece and the limit switch stopping it from going to high.

  • WHICH MACHINE SHOULD I BUY, THE GREENBULL OR BLACKFOOT?

    The greenBull can range is routing width sizes of 5 feet and 6 feet. The blackFoot has a 4 foot routing width.

    Previous Solution:
    The greenBull machine has a sturdier gantry than the blackFoot, so you can be more agressive with the cutting feedrate (cutting speed). The blackFoot is also a good machine, but it all comes down to the speed at which you want to produce the fabrication

    The spindle is also highly recommended for it's quietness and easier cleanup (no fan blowing the dust in the air)

  • MY LIMIT SWITCHES ARE TRIGGERING AT RANDOM.

    Are you using shielded wire? If so, take the shield to ground. If there are any other wires in the cable that is not being used, ground those as well. The customer can also try moving the cables as far away as possible from the motor wires and motors.

  • CONVERT BLACKFOOT 3D PRINTER

    To convert our CNC machine into a 3D printer, an extruder would need to be attached to the z-axis. The extruder could be added next to the spindle, or the spindle can be removed and the extruder replace the spindle.

    The former would be an interesting combination where you would be able to extrude plastic and then run the spindle afterwards to do some finishing passes; however, the weight of the spindle would reduce the performance. Without the spindle, the z-axis will move with reduced inertia.

    The electronics would be mostly the same with the addition of an extruder controller and a main controller board to control the existing drivers.

    You can find all of the 3D printer parts here:

    If you need help with fashioning a mount for the FDM extruder, please let us know.



    User response:
    Yes what type of mount would I need for the FDM extruder ? Thanks Gary

    User response:
    Could you be a little more specific on what type of main board I'll need to purchase the board I'm using now for my router is a serial port interface purchased from you. Thanks Gary

    BYCNC response:

    The 3d printing board we sell works with an Arduino Mega 2560. We sell the Arduino here:

    https://buildyourcnc.com/Item/3D-Printer-Component-electronicsAndMotors-electronic-component-arduino-mega-2560-FDMElectronics

    and the board here:

    https://buildyourcnc.com/Item/3D-Printer-Component-electronicsAndMotors-3d-printer-mainboard-FDMElectronics-3dprintermainboard

    We sell the extruder itself here:
